Knuckle Joint (mechanical)
A knuckle joint is a mechanical joint used to connect two rods which are under a tensile load, when there is a requirement of small amount of flexibility Stiffness is the extent to which an object resists deformation in response to an applied force. The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is. Calculations The stiffness, k, of a bo ..., or angular moment is necessary. There is always axial or linear line of action of load. The knuckle joint assembly consists of the following major components: # Single eye. # Double eye or fork # Knuckle pin. At one end of the rod a single eye is formed and a double eye is formed at the other end of the rod. Both, single and double eye are connected by a pin inserted through the eye. The pin has a head at one end and at other end there is a taper pin or split pin. For gripping purpose, the ends of the rod are of octagonal forms. Now, when the two eyes are pulled apart, the pin ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
